Fill Dirt in Lake Oswego, OR

In 2025 in the Lake Oswego/West Oregon area, expect screened or clean fill-dirt to run roughly $12 to $30 per ton, depending on supplier, moisture and screening. Converted to volume, that is about $15 to $36 per cubic yard (soil density varies by moisture and compaction). Hello Gravel shows transparent local pricing during checkout and has a 3-ton minimum for most deliveries.

Hello Gravel generally requires a 3-ton minimum order. Many Lake Oswego deliveries qualify for free delivery, but some locations, restricted access sites or uphill/difficult drops can add fees (commonly $0 to $150 or more depending on distance and site conditions). Always check checkout for exact delivery charges and schedule options.

You may need a permit for importing fill depending on the amount and whether it changes grades or affects drainage. The City of Lake Oswego Development Services handles grading and stormwater rules, and parts of the city are also in Clackamas or Multnomah County; check with the city or county before ordering large volumes or altering slopes. When in doubt, contact the City of Lake Oswego and your county planning department to confirm permit thresholds and requirements.

West Oregon's wet winters and clay-rich pockets can cause fill-dirt to retain water, settle and lose load-bearing capacity if not properly drained and compacted. For areas exposed to frequent wetting, contractors typically prefer free-draining structural fill or crushed rock below the surface to prevent saturation. Plan for proper drainage and compaction to avoid long-term settling or mud issues.

Most Lake Oswego contractors do not recommend using loose fill-dirt as the primary base under driveways. Instead they specify a compacted structural base—often 3/4u0022 minus or 3/4u0022 to 1-1/4u0022 crushed rock—installed in 6-8u0022 lifts and compacted to about 90-95% of Standard Proctor. If fill-dirt is used to raise grade, it should be placed in controlled lifts and inspected/compacted by a contractor or engineer to meet local load and drainage needs.

To calculate volume: area (sq ft) x depth (ft) / 27 = cubic yards. For 100 sq ft at 6 inches (0.5 ft), that is 100 x 0.5 / 27 = about 1.85 cubic yards. Using a typical fill-dirt conversion (about 1.2 to 1.4 tons per cubic yard) that equals roughly 2.2 to 2.6 tons. Local suppliers and Hello Gravel price and sell fill-dirt by the ton (check product listing), so convert your cubic yards to tons before ordering and remember the 3-ton minimum.

Yes, some local suppliers offer screened or clean fill-dirt (reduced organics and large debris) while others sell bulk rough fill. Spreading and compaction services are sometimes available through local contractors or as an add-on arranged by suppliers, but driver tailgate spreading is at the driver's discretion and is not guaranteed. For a finished base or engineered compaction, plan to hire a local contractor or request compaction services explicitly during ordering if available.

Standard Hello Gravel lead time is 2+ business days, but in West Oregon rainy seasons and peak landscaping months (spring and early summer) can push lead times to a week or longer. Wet weather and muddy job sites can also delay deliveries or limit where trucks can dump, so order earlier in high-demand seasons and include site notes about access and drainage when you schedule delivery.

Fill-dirt is usually less expensive up front than crushed rock or engineered structural fill, but it is more likely to settle, retain moisture and fail as a driveway base over time. Crushed rock or engineered fill costs more but provides better drainage, compaction and long-term stability for driveways and pads. For driveways in Lake Oswego's wet climate, most contractors recommend a crushed-rock base over plain fill-dirt for durability.

On slopes in Lake Oswego, control erosion by using terraces, retaining walls, geotextile fabric, and planted groundcover or mulch to stabilize soil. Install swales, catch basins or rock drains to route runoff away from structures and avoid placing loose fill near creek buffers or steep drop-offs; check city stormwater rules for protected areas. For steeper slopes or large fills, consult a civil engineer or the city for required permits and recommended stabilization methods.
